Hello, firstly i just want to start by saying thank you anyone who can help me with this.

I am compiling a record of family who served in WWI and WWII in various campaigns, could any kind person tell me where i can confirm the details of ancestors in the Royal Indian Army? In specific the RIASC?

The person in question is my great grandfather and his details (that i have) are as follows:

Name: Ghulam Hassan Khan Niazi -K.S
Rank: Lt.
Service Number: IEC 2168
Parent Corps: Royal Indian Army Service Corps
Company/Bt: Unknown.
Campaign Medals: All i know is based on the paperwork i have, he had received a 1939-1945 Star & 1939-1945 War Medal and a Bronze Oakleaf.

@ OlBaldy: Thank you very much for the link to the Gazette, at least that confirms the service number and corps info i have is correct.
@ Bigjimangley, thank you for the info i will try to contact the War Museum.
